Why carry out a relationship test?

Generally, relationship DNA testing is a means of establishing paternity in cases where the father is not available and therefore, a straightforward paternity test is not an option. In such cases a grandparentage test or an avuncular DNA test can substitute a paternity DNA test. Siblings may also do a sibling DNA test, which will establish the extent of the sibling relationship: half siblings, full siblings or not siblings. Below are the relationship DNA tests we offer. This said, no relationship test will provide the same conclusive results that can be given in a home paternity test.

What will the results of a relationship test tell me?

This is not a clear-cut question with a single answer as different tests will give you different answers and not all tests are equally accurate. Some tests might just give you a probability of relationship and others might give you a definite yes you are related result. Again, for more information and details about any of our DNA tests, you can contact our team who will give you all the information you need.

How do I go about deciding on the type of test to carry out?

When you look through our range of relationship testing services, you will probably immediately know which one you require as soon as you skim the first sentence. However, we can give you 2 basic questions to help you decide on your test:

  • What do you want to establish?
  • Who is available for testing?

What you wish to establish refers to what you hope to find out with the DNA test result. Have a clear question in mind, for example “I want to know if this woman is my biological grandmother” or “I want to find out if my brother and I share the same father”. This will help decide if you need a siblings DNA test, avuncular test etc.

Who is available for testing is crucial and an often overlooked factor when deciding on a relationship test. You may want to know whether you and your brother share the same father but is your brother willing to submit his sample? homeDNAdirect suggests you contact our customer support team to help you decide on the best relationship test.
